I-Weld Neck Flanges kanye ne-Slip On Flanges--BS3293

I-British Standard BS 3293: I-1960-Carbon Steel Pipe Flanges (ngaphezu kwamayintshi angama-24 usayizi wegama) we-Petroleum Industry, ihlanganisa i-Class 150lb kuya ku-600lbweld neck flangesfuthislip kuma-flanges.

Okulandelayo kuzokwethula ubukhulu kanye nokubekezelelana kweukushisela intamo flange kanye nentamo flat welding flangekuBS3293.

I-BS3293 yokushisela intamo kanye nokushelela ku-flange kungokwesistimu evamile ye-flange yaseMelika.Iwukubonakaliswa kwe-American flange ejwayelekile (ephinde yaziwe ngokuthi indlela ye-ANSI) kanye nokukodwa kwama-flange asetshenziswa kakhulu ezintweni zokusebenza noma epayipini.

I-BS 3293:1960 iyimpahla nosayizi.Leli zinga lisebenza kuphela ku-carbon steel efoshiweI-Slip-on flange kanye ne-welded nentamo flange yobubanzi obujwayelekileAmayintshi angu-26 nangaphezulu ku-petroleumUkumba izimboni, ukubhowula, ukuqeda nokushuba
Ubukhulu busebenza naseziphethweni ezibalulekile.
Ama-flange ama-valve nokufakwa.Izinhlobo ezine zama-flange zinikeziwe, okuyi-class150, 300, 400 kanye ne-600. I-BS 3293:1960 ayifaki: izilinganiso zokucindezela / izinga lokushisa;Igama lereferensi ye-flange lisetshenziselwa izinjongo zokuhlonza
Ireferensi ephambanayo kuphela: BS 1503, BS 1560, BS 1750, BS 3351, ANSI B16.20, ASTM A 105

Umehluko phakathi kwe-Weld Neck Flanges kanye ne-Slip On Flanges
1. Amafomu e-weld ahlukene:
Ukuhlolwa kwe-Radiographic kungenziwa kuma-welds we-flange ye-wick butt welding, kodwa hhayi i-flange ye-welding flat.Ifomu le-welding ye-neck butt-welding flange kanye nepayipi i-weld circumferential, kanti uhlobo lokushisela lwe-flange welding flat kanye nepayipi i-fillet weld.I-Butt welding iyi-butt circumferential weld, futhi i-flat welding ingama-weld amabili ajikelezayo.Umehluko phakathi kwalokhu okubili ukuthi insimbi yokushisela ehlanganisa i-flange yokushisela izinqe kanye nombhobho ngeye-Class B seam, kanti i-weld ehlanganisa i-flange yokushisela izinqe kanye nombhobho nge-Class C seam.
2. Izinto ezihlukile:
Izinto ze-neck butt welding flange ngokuvamile zenziwe ngezingxenye zensimbi ezenziwe ngomshini ngomshini.Impahla ye-slip-on welding flange enentamo yenziwe ngepuleti lensimbi elijwayelekile elinogqinsi oludingekayo ngomshini.
3. Izingcindezi ezihlukile:
Umfutho ojwayelekile we-neck butt-welding flange ngu-1-25MPa, ophakeme.Ukucindezela okulinganiselwe kwe-flange ye-welding flat yentamo yi-0.6-4MPa.Uma kuqhathaniswa ne-neck flat welding flange, izinga layo lokucindezela liphansi futhi ikhono layo lokuzivumelanisa nengcindezi nalo liphansi.
